On January 20, 1999, the California Digital Library (CDL) opened its "digital doors" through which users can access the online library catalogs of the University of California system, as well as an array of digital resources such as indexes and databases, electronic journals and texts, archival finding aids, and digitized photographs and images. The CDL is intended primarily for University of California users, but many resources are freely available to any who enter. Users who access the site from another large university may have an easier time, since their campus might also be a participant in various electronic journal licensing agreements, such as MUSE and JSTOR. For example, browsing by arts & humanities as subject and electronic journals as format retrieved a list of 35 journals, many available in full-text, with a warning that if a user cannot access the text, his or her campus may not subscribe to the journal. CDL also provides access to the Online Archive of California, a searchable online union database of finding aids for archival collections from archives and special collections departments in over two dozen California institutions such as Stanford, the California Historical Society, and the California State library. Many of the finding aids in the Online Archive of California link to images and texts.
